Round the World Trip (storage advice)

Done some research. Purchased a netbook. Should come this week. Its got a 250 GB HD and 2 GB DDR3 Ram. Figured it was the best option. I am gonna do exactly what you say. Pick up a second external drive so I can have copies on both.

Then 3 months into my trip when my friend meets me for 1 months I will have them bring me an HD to send back with him.
